Hotel prices in Arlington during Final Four weekend will be double what they were a year ago, according to data from the online travel site Trivago. And they’ll be up 40 percent in Dallas and nearly 20 percent in Fort Worth.

Hotel rates typically head skyward during a big sporting event in North Texas. But often Dallas, with its collection of high-end hotels, sees the biggest jump.

“We are all going to benefit … from this, the whole area,” said P.J. Patel, general manager of the Wingate by Wyndham hotel in Arlington. “We wish we could have more of these events in the future.”

Patel declined to discuss specific price jumps at his hotel, which is 95 percent booked. He said overall he does not see the prices as out of line with increases in other major cities when sports fans flow in.

Anywhere there’s an event of this size, “the prices double,” he said.

Compared with previous Final Fours, the Arlington rate jump is at the high end of the range.

When hoops fans filled Atlanta hotels last April 7, the night before the NCAA title game, rates jumped 97.2 percent from the previous year, according to STR, formerly Smith Travel Research. The gain was 22 percent in New Orleans in 2012.

The Trivago data is based on prices quoted in thousands of consumer searches on the company’s website. So it includes prices charged at the major hotels in Dallas, Arlington and Fort Worth.

Based on data from Priceline.com, average daily hotel rates have increased about 40 percent regionwide compared with last year. Four-star hotels experienced the biggest jump, from $151 to $235 a night on average, according to priceline.com.

Many hotel lobbies can expect to see a sea of Wildcat blue.

For the Final Four, priceline .com data show that Kentucky will have about twice as many room nights booked as Wisconsin and three times as many as Connecticut, said spokeswoman Leslie Cafferty.

For the championship game, Kentucky fans booked twice as many rooms as travelers from Florida.

In both Dallas and Arlington, three-star hotels are reaping four-star prices.

A spot check Wednesday of Hotels.com found one 3.5-star inn — Hotel Indigo in downtown Dallas — with rooms for $284 a night. That’s more than $100 more than an average nonchampionship rate.

The Hilton Garden Inn Dallas-Arlington listed a rate of $449.

And many last-minute callers are finding there are no more rooms, even at the steeper prices

TownePlace Suites in Arlington is booked solid, but only about 25 percent of that business is a symptom of March Madness. The long-term stay hotel already was largely filled with long-term guests.

“Within the last few days, as people know the teams, we’ve had triple the number of calls,” said Matt Hallinan, the general manager. He said he’s had to turn people away.
